Environmental conditions and timing determine tree survival, not treatment alone

Crutchfield's core argument is that tree health is determined by the convergence of three factors—host vulnerability, pathogen presence, and environmental conditions—and that professional intervention must target the weakest link in this triangle rather than applying blanket treatments. He further argues that timing of intervention (seasonal windows, early detection, preventive action) is often more valuable than the intervention itself, and that property owners' failure to act quickly at disease onset creates cascading financial and ecological consequences.
